Scope
This document, used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed or self-propelled machines that have a combination of two or more of the following functions: loading, mixing, chopping and distributing silage and/or other feedstuffs or materials used for animal bedding such as straw, to be used by one operator only. It includes those fitted with a built-in loading crane. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer.
Purpose
Animal feeding operations on farms, in order to provide proper nutrition, take various feedstuffs and other supplemental ingredients to form a totally mixed ration. The machinery used for these processes have some elements that can be sources for risk of harm to the operator. Providing principles for design to reduce risk of harm and appropriate protective measures are seen as useful to the designer and intended to provide safe use for the operator.
